### Bottom visible
Use `scrollY`, `scrollHeight` and `clientHeight` to determine if the bottom of the page is visible.
```js
const bottomVisible = _ =>
document.documentElement.clientHeight + window.scrollY >= document.documentElement.scrollHeight || document.documentElement.clientHeight;
// bottomVisible() -> true
```
